UNITED STATES PATENT OEEIoE.

JOHN M. THATOHER, OF BERGEN, NEW JERSEY.

FIRE-PLACE HEATER.

Specification forming part of Letters Patent No. 91,287, dated June 15, 1869.

To all whom it may concern:

Be it known that I, JOHN M. THATOHER, of Bergen, in the county of Hudson and State of New Jersey, have invented a certain new and useful Improvement in Fire-Place Heaters; and I do hereby declare that the following is a full and correct description thereof, reference being had to the accompanying drawings, and to the letters of reference thereon.

Figure 1 of the drawings is a front view of my improved fire-place heater as set in a fireplace; Fig. 2, a longitudinal section; Fig. 3, a horizontal section; Fig. 4, a plan view, with mantel and chimney broken away; Fig. 5, view of the slicer, or plate to be introduced into the fire-pot under the feeder, to hold up the coal that is unconsumed when the clinkers and ashes, &c., in lower part of grate are to be removed; Fig. 6, plan View of grate; Fig. 7, front view of grate.

In base-burning stoves and heaters great trouble is sometimes experienced when the fire goes out, leaving the feeder full, or partly full, of coal; also, when it is desired to clean out the fire above the grate and remove clinker and slate and other matters, or to introduce kindling below the coal in the grate. To remedy this difficulty, I have devised means to hold up the coal in the fire-pot and feeder while kindling is being introduced below, or the clinkers, &c., are removed.

For this purpose I have made a horizontal opening, m, in the fire-pot, of sufficient width, and at the proper height to introduce the slioer a, Fig. 5, by opening the door at, which is also of sufficient width for that purpose.

The slicer a, which is a flat plate of metal,

with a handle of nearly the width of the inner diameter of the fire-pot, being pushed horizontally through the coal in the fire-pot until it reaches the back of the same, will hold up the coal above it and prevent it from pressing down to interfere with removing clinkers and unconsumed matter below through the clinker-cleaning passage, or by tipping the grate, and also holds up the coal above to permit the introduction of kindling, if desired.

Although I prefer to put in the slicer below the top of the fire-pot, as described, yet, if an opening be made of sufficient width to intro duce the slicer above the fire-pot, in such manner that it can pass under the feeder and hold up the coal therein when desired, it will be a great advantage.

I have described this invention as embodied in a fire-place heater, but it is obvious that it is equally applicable to base-burning stoves and heaters of other kinds which have a feeder.

The drawings represent other improvements in fire-place heaters, which are also of my invention, but which it is not necessary to describe in detail, as they are the subject of a separate patent.

I claim- In combination with the fire-pot and feeder, the slicer, for holding up the coal, and a suitable opening to introduce the slicer, substantially as described.

JOHN M. THATCHER.
